UK long range weather forecast

A dry start to the period Saturday staying mainly dry and bright in parts of the south and east through the day, outbreaks of rain possible across the northwest at first, spreading eastward. Turning windier again with a chance of coastal gales in the west. Through the first half of the period it will settled, especially in the west. Initially cold, with chance of overnight rural frost, and showers wintry over highest ground. Temperatures trending upwards through the period. The rest of October will be dominated by weather arriving from the Atlantic. Often unsettled and windy, with outbreaks of rain. Wettest in the north and west. Briefer dry interludes. Driest conditions likely across south and southeastern areas. Winds lighter here, with risk of overnight fog at times.

Updated:

The beginning of this period will likely remain unsettled with many systems arriving from the Atlantic. It will remain wet and windy with the wettest and windiest conditions in the north and west. Driest conditions across the south especially the southeast with lighter winds but the risk of overnight fog at times. From early to mid-November increasing chance of settled weather but confidence of this is very low. Temperatures are likely to be warmer than average for most. Perhaps some colder spells and an increasing chance of frost and fog towards the end of this period but confidence of this is very low.
